Overview

What this migration involves

Moving from Fat Free CRM to Monday.com CRM is a structural migration from a self-hosted Rails database into a SaaS board-based CRM. Fat Free CRM has no documented REST API, so we connect read-only to its underlying MySQL, PostgreSQL, or SQLite database to extract relational data intact, including join tables for account-contact, opportunity-contact, and campaign-contact associations. Monday.com CRM uses a board-based architecture where CRM objects (Contacts, Companies, Deals, Leads) live as Items on custom Boards with typed Columns rather than as native CRM objects with fixed schemas. We create those Boards and Columns before migration, preserve link-table relationships using Monday.com Item connections or a reference board, and migrate custom fields as custom Column types. Attachments live on the Fat Free CRM filesystem and do not migrate automatically; we enumerate every attachment reference and deliver a file inventory for manual copy. Fat Free CRM user and group IDs have no meaning in Monday.com, so we export a user roster and the customer's admin creates Monday.com team members and reassigns ownership post-migration. Workflows, plugins, and automation configurations do not migrate; we deliver a written map for the admin to rebuild them as Monday.com Automations.

Why teams make this switch

Two sides of the same decision

Leaving

Fat Free CRM logo

Fat Free CRM

What's pushing teams away

  • The user interface feels dated compared to modern SaaS CRMs, and G2 reviewers consistently rate the UX as needing significant improvement.
  • Community development has slowed — Bitrix24's comparison page explicitly notes it is unclear whether Fat Free CRM is still actively maintained, raising long-term support concerns.
  • No native public API means third-party integrations require direct database access or custom Rails code, complicating connections to email, calendars, or other tools.
  • Lacks the reporting depth, automation builder, and sales intelligence features that teams outgrow as they scale beyond basic contact and opportunity tracking.
  • Hosting, maintenance, security patching, and upgrades fall entirely on the customer, creating hidden operational overhead that grows over time.

Choosing

monday CRM logo

monday CRM

What's pulling them in

  • Users praise the board-based visual interface for making pipeline stages immediately legible to non-technical team members without CRM training.
  • The no-code automation builder lets sales ops teams create lead routing, stage updates, and email triggers without developer involvement.
  • Integration ecosystem connects to Slack, Gmail, Outlook, and Zapier with minimal configuration, reducing friction for teams already using these tools.
  • The flexible column system lets teams build custom CRM views — deal value, close date, lead source — without needing a developer or pre-defined schema.
  • Teams already using monday Work Management can layer CRM features onto existing boards rather than starting from scratch.

Object mapping

How Fat Free CRM objects map to monday CRM

Each row shows how a Fat Free CRM object lands in monday CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Fat Free CRM

Account

maps to

monday CRM

Company Board / Item

1:1
Fully supported

Fat Free CRM Accounts map to Items on a Companies Board in Monday.com CRM. We extract name, website, phone, billing address, and assigned user from the accounts table, then create Items with corresponding Column values. Account-Contact associations from the contact_accounts join table migrate as Monday.com Item Connections or a reference Items Board, depending on the customer's preferred relationship structure.

Fat Free CRM

Contact

maps to

monday CRM

People Board / Item

1:1
Fully supported

Fat Free CRM Contacts map to Items on a People Board. Standard fields (first name, last name, email, phone, title) map to typed Columns. The contact_accounts join table links each Contact Item to its corresponding Company Item via Monday.com Item Connections. We resolve the Account reference before inserting Contacts to satisfy the relationship at migration time.

Fat Free CRM

Lead

maps to

monday CRM

Leads Board / Item

1:1
Fully supported

Fat Free CRM Leads are distinct from Contacts with status, source, rating, and assigned user fields. We map them to a Leads Board in Monday.com with Columns for status, lead source, rating, and any custom fields. Lead-Account associations migrate as Item Connections. The customer's admin decides whether to merge Lead Items into the People Board post-migration or maintain a separate Leads Board.

Fat Free CRM

Opportunity

maps to

monday CRM

Deals Board / Item

1:1
Fully supported

Fat Free CRM Opportunities link to an Account, track stage, amount, probability, and close date, and have an opportunity_contacts join table. We create a Deals Board with Columns for deal name, stage (mapped from Fat Free CRM stage values to Monday.com Status Column), amount, probability, and close date. The opportunity_contacts join table maps to Item Connections linking each Deal Item to the relevant Contact Items.

Fat Free CRM

Task

maps to

monday CRM

Tasks Board / Item

1:1
Fully supported

Fat Free CRM Tasks belong to a user and optionally to an Opportunity or Contact, with title, body, due date, category, and completion status. We migrate both open and completed Tasks as Items on a Tasks Board, using a Status Column for completion state and Date Columns for due dates. Task-Contact and Task-Opportunity associations migrate as Item Connections to preserve the original linkages.

Fat Free CRM

Campaign

maps to

monday CRM

Campaigns Board / Item

1:1
Fully supported

Fat Free CRM Campaigns track name, status, budget, and target metrics. We create a Campaigns Board with Columns for those fields. Campaign-Contact memberships (tag subscriptions and campaign_contacts join table) migrate as Item Connections linking each Campaign Item to the relevant Contact Items, preserving the many-to-many relationship.

Fat Free CRM

Tag

maps to

monday CRM

Label / Tag Column

lossy
Fully supported

Fat Free CRM uses the acts_as_taggable gem to store global tags across Contacts, Accounts, Opportunities, and Leads. Since Monday.com CRM has no native global tagging across boards, we either map tags to Monday.com Labels (on the respective boards) or create a Tags Board with Items representing each tag, linked back to their source records via Item Connections. The customer chooses the strategy during scoping.

Fat Free CRM

Custom Field

maps to

monday CRM

Custom Column

lossy
Fully supported

Fat Free CRM custom fields on Accounts, Contacts, Leads, and Opportunities are stored in extension tables or serialized fields. We extract the field definitions and values, then create matching custom Columns in Monday.com with the appropriate type (text, number, date, dropdown, checkbox). Dropdown options migrate as Status Column values. We cannot migrate formula-based custom fields from Fat Free CRM; these require manual recreation as Monday.com formula columns.

Fat Free CRM

Attachment

maps to

monday CRM

File (documented for manual copy)

1:1
Fully supported

Fat Free CRM stores uploaded files on the host filesystem or a configured S3 bucket, not in the database. We enumerate every attachment record (filename, path, associated record ID, record type) and deliver a file inventory CSV. The customer copies binary files to Monday.com storage manually post-migration and reattaches them to the corresponding Items. We cannot extract binary file content through the standard database connection.

Fat Free CRM

User

maps to

monday CRM

Team Member

lossy
Fully supported

Fat Free CRM Users have login credentials, role (admin or user), and team membership. We extract the full user roster (name, email, role, team) as a reference table. Monday.com Team Members are provisioned by the customer's admin in workspace settings; we cannot create them without write access to the destination. The admin creates Monday.com accounts and we provide the mapping to reassign record ownership after migration.

Pair-specific challenges

  • No Fat Free CRM public API forces direct database extraction

    Fat Free CRM exposes no documented REST or GraphQL API. All extraction requires a read-only connection to the underlying MySQL, PostgreSQL, or SQLite database. The customer must provide database credentials and confirm the database type before scoping begins. If the Fat Free CRM instance has been heavily customized with non-standard table names or plugin-created tables, we run a schema discovery pass against the live database to capture the full table inventory before writing any extraction queries. Direct database access is not required for Monday.com, which has a fully documented API we use for the import phase.

  • Plugin-extended schema may add columns to core tables

    Fat Free CRM's plugin system can add columns to core tables (accounts, contacts, opportunities) or create entirely new tables for custom functionality. We run a schema discovery phase against the live database before extraction to identify any plugin additions not present in the base Rails schema. Undiscovered plugin columns that appear after extraction will surface as missing fields in the Monday.com destination and require a supplementary migration pass. Customers with custom plugins must enumerate them during scoping so we can include them in the discovery phase.

  • Attachment files do not migrate automatically

    Uploaded files in Fat Free CRM are stored on the server's local disk or a configured S3 bucket, not in the database. Our database connection captures attachment metadata (filename, path, associated record type and ID) but cannot extract binary file content. We deliver a complete file inventory CSV listing every attachment, its source path, and its linked record. The customer is responsible for copying files to Monday.com storage and reattaching them to the migrated Items post-migration. If the source server will be decommissioned before files are copied, data loss is permanent.

  • Fat Free CRM Users and Groups have no Monday.com equivalent

    Fat Free CRM internal user IDs and group IDs are not portable to Monday.com. We export the full user roster and group membership as a reference table, but migration cannot create Monday.com Team Members or configure workspace permissions without write access to the destination. The customer's Monday.com admin provisions Team Members in workspace settings before cutover, and we provide a record-ownership mapping table so the admin can reassign Items to the correct owners after migration. Groups do not map to a specific Monday.com object; we recommend mapping them to Teams if the group structure is important for access control.

Migration approach

Six steps for a successful Fat Free CRM to monday CRM data migration

  1. Database discovery and schema inventory

    We connect read-only to the Fat Free CRM database (MySQL, PostgreSQL, or SQLite as confirmed during scoping) and run a full schema discovery pass. We enumerate all tables, columns, join tables, plugin-added columns, and custom field definitions. We also count records per object (Accounts, Contacts, Leads, Opportunities, Tasks, Campaigns), enumerate attachment paths, and export the user and group rosters. This inventory drives the migration scope document and identifies any plugin-extended schema requiring additional mapping work.

  2. Monday.com board and column design

    We create the destination Boards in Monday.com (Companies, People, Leads, Deals, Tasks, Campaigns) with typed Columns matching the Fat Free CRM field inventory. We configure Status Columns for stage/status values, Date Columns for due dates and close dates, Number Columns for amounts and probabilities, and Dropdown or Labels Columns for picklist fields. For custom fields discovered during schema review, we create matching custom Columns. Item Connections are provisioned on Deals and Campaigns boards to receive the opportunity-contact and campaign-contact relationship data.

  3. Test migration in a staging Monday.com workspace

    We run a full migration into a staging Monday.com workspace using production-like data volumes. The customer spot-checks 25-50 randomly selected Items across each Board against the Fat Free CRM source records for field accuracy, relationship integrity, and attachment reference completeness. Any mapping corrections (wrong column type, missed custom field, relationship direction error) are documented and corrected before the production migration begins. Attachment file inventory is validated against the filesystem.

  4. User and group roster handoff

    We deliver the full user and group roster as a structured reference table. The customer's Monday.com admin creates Team Members in workspace settings, assigns appropriate workspace roles (member, viewer, admin), and maps each Fat Free CRM user to a Monday.com Team Member by email. We cannot provision Monday.com users without destination write access; this step requires admin action and is a gate for production migration.

  5. Production migration in dependency order

    We run production migration in record-dependency order: first Companies (Accounts), then People (Contacts) with Account connections resolved, then Leads, then Deals with Contact connections resolved, then Tasks, then Campaigns with Contact connections resolved. Tags migrate as Labels on each Board or as a Tags Board depending on the customer's chosen strategy. Custom fields migrate as custom Columns. Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, attachment recovery, and automation handoff

    We freeze Fat Free CRM writes during the cutover window, run a final delta migration for any records modified during the window, then confirm Monday.com as the system of record. We deliver the complete attachment file inventory CSV with source paths and linked Item IDs. The customer's team copies files to Monday.com and reattaches them. We deliver a written automation inventory documenting every Fat Free CRM plugin-based workflow with a recommended Monday.com Automation equivalent for the customer's admin to rebuild.

Platform deep dives

Context on both ends of the pair

Fat Free CRM logo

Fat Free CRM

Source

Strengths

  • Zero licensing cost — fully open source under MIT license with no per-user or subscription fees.
  • Complete source code access allows deep customisation of data models, views, and business logic without vendor lock-in.
  • Lightweight Ruby on Rails stack runs on commodity hosting (VPS, Heroku) with standard relational databases.
  • Active community and plugin architecture provide extension points for webhooks, time tracking, and record merging.
  • Self-hosted model ensures full data ownership and no third-party data retention concerns.

Weaknesses

  • No native public API — integrations require direct database queries or custom Rails development, limiting third-party tool connectivity.
  • Dated user interface consistently cited in reviews as a friction point compared to modern SaaS CRM experiences.
  • Slowing development activity raises concerns about security patches, Rails compatibility updates, and long-term viability.
  • Operational burden of self-hosting (server management, backups, upgrades, security) falls entirely on the customer.
  • Limited reporting, automation, and sales intelligence features compared to commercial CRM platforms.

Destination

Strengths

  • Board-based UI makes pipeline stages and deal progress visually obvious without training.
  • No-code automation builder requires no developer resources to create lead routing and stage-triggered actions.
  • Flexible column system supports custom CRM fields without schema changes or admin involvement.
  • Integrates natively with Slack, Gmail, Outlook, and Zapier with minimal configuration overhead.
  • Layered product means teams already on monday Work Management can add CRM without migrating existing data.

Weaknesses

  • No native Contacts object separate from Items — contacts are managed inside a CRM module's People feature.
  • Pipeline and deal relationships use a flat item model rather than a relational object model, making complex CRM associations awkward.
  • Automations are plan-gated (250 actions/month on Standard, 25,000 on Pro) and the legacy Recipe system is being deprecated.
  • Customization and advanced views (Chart, Formula, Dependency) are locked behind Pro and Enterprise tiers.
  • Per-seat pricing with non-refundable annual billing creates cost lock-in risk during migration.

Most migrations land between one and three weeks for accounts under 5,000 Contacts, 2,000 Accounts, and 1,000 Opportunities with no plugin-extended schema. Migrations with large task histories (over 100,000 records), multiple custom field definitions, complex campaign-contact join tables, or plugin-created database columns move to three to five weeks because of the schema discovery overhead and custom column configuration per Board.
